6.5 speaker box bookshelf

i used 3/4" plywood but you can use whatever material you like. the cut files are 1 the layers to be stacked and 2 the top/bottom. all tool paths are meant to go entirely through. i picked up dowels at the hardware store and i liked using these mainly to keep it aligned while assembling. i would suggest using a silicone based glue toward the inside of the box and a construction adhesive toward the outer edge. solid slabs of wood are a much better option if you have them available both for avoiding plywood voids and appearance if you intend to use this design as a bookshelf speaker.
